PAUL RAOULT, OF LIEGE, BELGIUM.

BIGGER FOR BEET AND OTHER ROOTS ELANTED IN LINES.

Applicati'ounled December 23, 1925, Serial No. 77,307, and in German-y February 14, 1925.

I *l My invention has for its object to provide Vand the features of novelty pointed out in the:

Cil

a machine of the character in which the penetration of the shares into the ground is automatically eected by the tractive effort of the drivingv means and the discharging 4of the extractedroots in. regular rows onV the ground d is effected by means of rotary rollers moving the roots into a screen fitted inside with a worm conveyor or the like.

The invention will now be fully described appended claim.

Reference is to be had to the Vaccompany- .ing drawings in which:

Figure -1 is a side elevation of a digger for a double line. Figure 2 is a plan view of the same and Figure 3 a cross-sectional elevation of the share frame shown in lFig.v 1.

,1 designates shares fixed to standards 2 carried by means of a shaft 3 having oppositely pitched sci-eu7 threads in order to regulate the distance between the two pairs of shares 1,. It is sufficient to turn a Wrench on the square end of the shaft 3 in order to cause the pairs of shares to approach or separate.

5 indicates parallel arms secured to the shaft 3 and rigidly connected to a sleeve 6 surrounding the axle 7 of the digger. v

' 8 indicates arms parallel to the arms 5 and pivoted at their rear'cnd to a shaft 9 connectbexes 11 of the frame 12 of the machine.

The sharesl are thus supported by means of a parallelogrannnic system oscillating on the axle 7 through the medium of the sleeve 6, which carries a leverV 13 connected to a traction ring 18 by means of a chain 14 passing over a roller 15 suspended at small distance from the frame 12 by means of asuspension bow 16, in order to prevent the forward end of the machine from lifting during thc digging. Towards its center, the shaft 3 is supported by meansof a slotted yoke 18, threaded at its upper end for receiving a screw 19,

which oscillates in a sleeve 20'carried by the .frame and 1s actuated by means of a hand- Wheel 21. The shaft 9.is also connected by means of a bar 22 to the end of a` cranked lever 23 keyed-on a shaft'24 journaled in' means whereby the shares 1 are automatically sunk down into the ground, when a tractive effort exerted on the chain 14 causes the upward oscillating of the sleeve 6 and thus the sinking down of the parallelogrammic systems around the axle 7. The lowering of the shares 1 is regulated for the same culture by operating the handwheel 21, but if the shares must be lifted momentarily, by Way of example, in order to permit the turning about of the machine, it is sufficient to operate thc cranked lever 23, Which Will cause the lifting of the shares..

In vorder to clean the roots andv for throwing them to one side of the machine, in regular rows, l fitI loosely to the ends of the axle 7 draft members 26, 26, the rear ends of which are secured to fences 27, 27. The fence 27 carries a bearing 28 in which is journaled a shaft 29 having fixed thereto a sprocket- Wheel 30 forming. a tightener for an endless drive-chain 31, receiving motion from a sprocket-Wheel 32 mounted on the axle 7, beyond the ground-wheels 33. The drive-chain 31 transmitsalso rotary motion contrary to the motion of the Wheels33, to a sprocket- Wheel 34, the axle of which carries a sprocket- Wheel 35 actuating by mea-ns of a drive-'chain 36 sprocket-Wheels 37 mounted respectively on the axles of Wooden rollers 38 extending behind the shares` 1. The l sprocket-Wheels 35, 37 With the drive-chain 36 are closed in a casing 39 carried by a plate 40 secured to the fence 27. The axles of the rollers 38 are thus journaled at one end in the casing 39, and at the other end in the casing 41 secured to the fence 27. AOn the Wooden rollers 38 are fixed laths 42 in order to facilitate the gripping of the extracted roots. The draft members 26, 26 are pivoted to the Wheeled axle 7, but are held in substantially fixed relation to the shares 1 by means of bars 43 secured to the fences 27, 27 and hanging on the shaft 9 of the share-standards 2.

Behind the rollers 38 is mounted a screen constructed of pipes 44 extending beyond the ends of the rollers 38. The pipes 44 are mounted in a bearer 45 supported by means of a cable 0r chain 46 connected to a cranked lever 47 held in the adjusted position by the perforated quadrant 25 and secured to a sleeve V48 surrounding the shaft 24. The bearer 45 carries a central shaft 49 of a Worm conveyer 50, to which the motion is imparted by means of a sprocket-Wheel 51 and a drivechain 52 passing over a sprocket-wheel 53 mounted on thewheeled-axle 7. Members 54 connect loosely the said axle 7 with the shaft 49 of the worin conveyor 50,

Through the medium of the described n'ieehanisn'i7 the heet roots elevated by means of the rollers 38 will tip olf round the upper roller and sink on the pipes 4A in order to come in Contact with the conveyer 50, which will cause the removing of the earth from the roots and the throwing of the roots in regular rows on Athe ground. lf the roots must be dexlivered fai from the digger, the screen may be made telescopic.

Having thus described the invention, What is claimed and desired to be secured by ters Patent is: Y

In a digger, the combination of a digging frame, a wheeled axle supporting the rear end of said frame,y share-carrying standards,

turning saidy screw for varying the .height of said standards. v

ln testimony whereof I aliix my signature.
